摘要：The diatom composition on some Charophyceae taxa was investigated in different freshwater ecosystems in Bosnia and Herzegovina, Croatia and Montenegro during 2007. A total of 91 taxa belonging to 37 genera were identified. The genus Gomphonema with 9 taxa was the most diverse, followed by Navicula (7), Nitzschia, Pinnularia and Gyrosigma (5). The number of taxa at the localities varied from nine in Lake Kalajli on Bjelašnica Mountain to 33 in the Trebižat River (both in Bosnia and Herzegovina). The most frequent taxa (found in more than three localities) were: Amphora ovalis, Cocconeis placentula, Gomphonema coronatum, Melosira varians, Navicula tripunctata, N. radiosa and Ulnaria oxyrhynchus. In total, 52 taxa appeared only in one particular locality.
